Public Types
enum	Illum {   I_NONE =-1, I_DIFFUSE =0, I_DIFFUSE_AND_AMBIENT =1, I_SPECULAR =2,   I_TRANSLUCENT =9 }
	MTL Illumination models, see the developer doc for info. More...
typedef QMap< QString, QStringList >	ParamsMap

Static Public Member Functions
static QVector< Material >	loadFromFile (const QString &filename)
	Loads all materials contained in an .mtl file. More...

Data Fields
enum StelOBJ::Material::Illum	illum
QString	name
	Name of the material as defined in the .mtl, default empty.
QVector3D	Ka
	Ambient coefficient. Contains all -1 if not set by .mtl.
QVector3D	Kd
	Diffuse coefficient. Contains all -1 if not set by .mtl.
QVector3D	Ks
	Specular coefficient. Contains all -1 if not set by .mtl.
QVector3D	Ke
	Emissive coefficient. Contains all -1 if not set by .mtl.
float	Ns
	Specular shininess (exponent), should be > 0. Default 8.0.
float	d
	Alpha value (1 means opaque). More...
QString	map_Ka
	The ambient texture map file path.
QString	map_Kd
	The diffuse texture map file path.
QString	map_Ks
	The specular texture map file path.
QString	map_Ke
	The emissive texture map file path.
QString	map_bump
	The bump/normal texture map file path.
QString	map_height
	The height map texture file path.
ParamsMap	additionalParams
	Contains all other material parameters that are not recognized by this class, but can still be accessed by class users this way. More...

Static Protected Member Functions
static bool	parseBool (const QStringList &params, bool &out)
	Parses a bool from a parameter list (like included in the ::additionalParams) using the same logic StelOBJ uses internally. More...
static bool	parseFloat (const QStringList &params, float &out)
	Parses a float from a parameter list (like included in the ::additionalParams) using the same logic StelOBJ uses internally. More...
static bool	parseVec2d (const QStringList &params, Vec2d &out)
	Parses a Vec2d from a parameter list (like included in the ::additionalParams) using the same logic StelOBJ uses internally. More...

Detailed Description

It uses QVector3D instead of Vec3f, etc, to be more compatible with Qt's OpenGL wrappers.

Member Enumeration Documentation

Illum

enum StelOBJ::Material::Illum

Deprecated:

If possible, do not use. Illum use is very inconsistent between different modeling programs

Member Function Documentation

loadFromFile()

static QVector<Material> StelOBJ::Material::loadFromFile ( const QString &  filename )

static

Does not check if the texture map files exist.

Returns

empty vector on error

parseBool()

static bool StelOBJ::Material::parseBool ( const QStringList &  params, bool &  out  )

staticprotected

Returns

true if successful, the output is written into out

parseFloat()

static bool StelOBJ::Material::parseFloat ( const QStringList &  params, float &  out  )

staticprotected

Returns

true if successful, the output is written into out

parseVec2d()

static bool StelOBJ::Material::parseVec2d ( const QStringList &  params, Vec2d &  out  )

staticprotected

Returns

true if successful, the output is written into out

Field Documentation

additionalParams

ParamsMap StelOBJ::Material::additionalParams

The key is the statement name (e.g. Ka, map_bump etc.), the value is the list of space-separated parameters to this statement

d

float StelOBJ::Material::d

-1 if not set by .mtl Note that both the d and Tr statements can change this value
